Scientist Hacks Together Eye-Tracker for £43

A pair of cheap webcams hacked together with some custom software can offer a similar level of motion-tracking as £20,000 pro systems, which one scientist says could revolutionise the lives of millions of disabled people.

The eye-tracking system and its software have a latency of just 10 milliseconds, allowing easy computer cursor control for those with physical disabilities, with winking operating as a mouse click. The concept is nothing new, but the budget price tag means such sci-fi computer control could be opened up to a whole new audience. [Guardian]
